TZM/TZF Solenoid Locking Switch - Thermoplastic Housing

Key Features

  • Solenoid-locking & spring-locking designs … controls access to hazardous areas until safe conditions exist.
  • Highly tamper-resistant … difficult to defeat with simple tools, tape, bent wires, etc. Reduces liability exposure.
  • “Positive-break” NC contacts … assure circuit interruption upon actuator key removal.
  • Conditional “safe” outputs … actuating key must be fully inserted and solenoid must be actuated to lock key before “closed” safety signal is provided.
  • Watertight design … meets IP67 environmental requirements.
  • High-strength, galvanized-steel actuator key … tolerates mechanical abuse without damage.
  • Rugged, corrosion-resistant housing … tolerates hostile environments.
  • Three optional key entry locations … rotatable actuator head provides installation versatility.
  • Independent actuator key position and locking pin position monitoring contacts … provide a higher degree of safety.
  • Padlockable key … for added security during equipment maintenance.
  • Meets rigid safety agency standards … BG, UL, CSA.
  • Wide selection of actuating keys … to meet diverse application requirements.
  • Special types for food industry … please consult factory.
Applications

The TZF/TZM Series is intended for use as a safety interlock switch on movable machine guards which must not be opened until dangerous conditions, which may exist after the removal of power, have abated. Such conditions are flywheel overrun, spindle momentum, unstable rest positions, etc. Typical applications are textile machines, stamping presses, articulating robot arms, mixing machines, metal working equipment, printing presses and packaging machinery

The TZF/TZM Series is designed for machines/work cells where access to a hazardous work area must be controlled until safe conditions exist. Their solenoid-latching feature permits locking a machine guard until dangerous conditions, which may exist immediately after removal of power, have abated. Solenoid-latching may be controlled by a time delay, motion detector, position sensor or other suitable component. 

The unit features independent actuator key (guard) position and solenoid-latching monitoring contacts. These permit the prevention of machine restart until the guard is closed and the solenoid-latching pin is in the locked position.

The TZF/TZM Series consists of an electromechanical safety interlock switch with “positive-break” contacts and a locking actuator key. In addition, the TZFS model features an auxiliary manual unlocking device … the latter provided to aid in installation and for use in the event of a power failure (when using the “unlocking by solenoid” model).
